““And then there are colors. The truth is that the brain knows far less about colors than one might suppose. It sees more or less clearly what the eyes show it, but when it comes to converting what it has seen into knowledge, it often suffers from one might call difficulties in orientation. Thanks to the unconscious confidence of a lifetime's experience, it unhesitatingly utters the names of the colors it calls elementary and complementary, but it immediately lost, perplexed and uncertain when it tries to formulate words that might serve as labels or explanatory markers for the things that verge on the ineffable, that border on the incommunicable, for the still nascent color which, with the eyes' other bemused approval and complicity, the hands and fingers are in the process of inventing and which will probably never even have its own name. Or perhaps it already does -- a name known only to the hands, because they mixed the paint as if they were dismantling the constituent parts of a note of music, because they became smeared with the color and kept the stain deep inside the dermis, and because only with the invisible knowledge of the fingers will one ever be able to paint the infinite fabric of dreams. Trusting in what the eyes believe they have seen, the brain-in-the-head states that, depending on conditions of light and shade, on the presence or absence of wind, on whether it is wet or dry, the beach is white or yellow or olden or gray or purple or any other shade in between, but then along comes the fingers and, with a gesture of gathering in, as if harvesting a wheat field, they pluck from the ground all the colors of the world. What seemed unique was plural, what is plural will become more so. It is equally true, though, that in the exultant flash of a single tone or shade, or in its musical modulation, all the other tones and shades are also present and alive, both the tones or shades of colors that have already been name, as well as those awaiting names, just as an apparently smooth, flat surface can both conceal and display the traces of everything ever experience in the history of the world. All archaeology of matter is an archaeology of humanity. What this clay hides and shows is the passage of a being through time and space, the marks left by fingers, the scratches left by fingernails, the ashes and the charred logs of burned-out bonfires, our bones and those of others, the endlessly bifurcating paths disappearing off into the distance and merging with each other. This grain on the surface is a memory, this depression the mark left by a recumbent body. The brain asked a question and made a request, the hand answered and acted.””
